A method of weight-filling a receptacle having a cylindrical neck and a collar extending around the neck, comprising the steps of suspending the receptacle by the collar and filling and weighing the receptacle while it is suspended, and a weight-filler device for filling, by means of a filler spout, a receptacle having a cylindrical neck and a collar extending around the neck. The device has a weighing device including a holding element having a top surface forming a support for the collar of the receptacle so that the receptacle extends vertically beneath the filler spout and is cantilevered out from a support member mounted on a structure to extend laterally therefrom and associated with a weighing sensor comprising an elastically flexible bar having one end rigidly secured to the structure and an opposite end connected to the support member so that the support member extends substantially horizontally irrespective of a presence of an absence of a container on the support member.

Automotive load cells having centralized, multi-axis, loose tolerance overload/limit stops provide improved strain gauge response. The modular, integrated stop assemblies magnify sensor substrate deflection by use of opposed concave (Belleville) springs are used in direct contact with the substrate to accommodate ±Z axis deflection and Mx/My moment angular rotation. A flanged guide member on the load stud permits a wide range of geometries. The substrate is thickened around the load stud hole and the outboard support bolt holes. Hollow rivets assist in design modularity. Strain gauges are placed at the yield zones symmetrically with respect to the X axis. The substrate hole Mx/My gap is larger than the stop bracket hole to insure a positive stop for Mx/My moments prior to yield. The inventive multi-axis stop assembly is used in any type load cell, including rectangular, thinned, notched, necked/dogbone, or cantilever substrates with any strain gauge layout configuration.

An attachment structure for installing a load sensor to a vehicle seat includes the load sensor having a plate-shaped strain unit and a strain gauge for detecting a strain of the plate-shaped strain unit. The load sensor is structured that one end of the plate-shaped strain unit is fixed to a seating portion of the vehicle seat and the other end of the strain unit is fixed to a vehicle body. Also, a strain portion is defined between each fixed end of the plate-shaped strain unit, and the strain portion is deformable in a vertical direction relative to the vehicle seat. In addition, a load input point from the seating portion is defined approximately at a central portion of the strain portion of the plate-shaped strain unit.

A tank weigh module includes a bottom plate that has two lower stop blocks protruding upwardly therefrom, and a top plate that has an upper stop block protruding downwardly therefrom into a space between the two upper stop blocks with a block free play clearance therebetween. A restraining pin is arranged to extend through aligned pin receiving holes in all of the stop blocks. In the lower stop blocks, the holes provide a tight friction fit for the pin, while the hole in the upper stop block has a larger diameter and provides a pin free play clearance. Motion of the top plate relative to the bottom plate in the back-and-forth Y-direction is limited to the extent of the block free play clearance. Travel of the top plate in the side-to-side X-direction and in the uplift Z-direction is restrained by the extent of the pin free play clearance. Tilting and twisting about the X-, Y-, and Z-axes are also limited by the pin interacting with the blocks and the blocks interacting with each other. A load cell is secured in position between the top and bottom plates by two fixed securing pins and a third removable securing pin attached to the bottom plate, whereby the securing pins are angularly offset by 120° from each other. The weigh module has a simple construction, installation, and servicing, and provides protection against excess uplift, side loading, and tilting while allow complete free floating operation in a normal operating range.

A scale can include a low capacity sensing mechanism operatively coupled to a load, wherein the low capacity sensing mechanism may detect movement of the load. A transfer mechanism can be operatively coupled to the low capacity sensing mechanism, wherein the low capacity sensing mechanism may enable the scale to weigh both relatively heavy loads and relatively light loads to a minor division resolution associated with the low capacity sensing mechanism.

A filler head (1) carried by the carousel of a rotary powder filling machine comprises a dispensing element (3) by which a predetermined quantity of powder material is directed into a container (2) positioned on a platform assembly (7, 5) carried by a hollow frame (13); the dispensing element (3) is interlocked to a dynamometer (15) housed in the cavity (14) of the frame (13) and controllable thus during the step of filling the container (2). The platform support (5) is associated with a first actuator (18) mounted at the bottom of the frame (13) and designed to separate the selfsame support (5) from the dynamometer (15), also with a second actuator (21) by which the container (2) is caused to shake in a direction (B) that causes the powder material to settle in the container (2) during the filling operation.

A weighing pan carrier (47) for a balance with a weighing pan and with a weighing cell that includes a load-receiving portion (11) and a stationary portion (12) has an overload protection device against excessive vertically directed forces that is releasably engaged with the weighing pan carrier. The weighing pan carrier (47) is fastened to the load-receiving portion (11) of the weighing cell and has on the other hand a fixed connection to the weighing pan. The weighing pan carrier (47) has a torque safety feature, which is integrated in the overload protection device and provides protection against excessive forces acting tangentially on the weighing pan and/or on the weighing pan carrier (47) in a direction perpendicular to the direction of the weighing load.

A scale equipped with a memory display section comprises, separately from a regular display section 19 for indicating a current measured value, additionally a memory display section 20 for indicating the current measured value as a previously measured value in a series of consecutive measurements, wherein a transfer unit 22 executes such a transfer operation that the current measured value indicated in the regular display section 19 can be indicated in the memory display section 20 as the previously measured value in a series of consecutive measurements. A person in charge of measurement no more needs to take the trouble of remembering in the brain or taking notes of the previously measured values in a series of consecutive measurements, such as an incremental measurement, but the current measuring work can be carried out simply by a visual recognition.

A weighing serving implement is disclosed. The weighing serving implement has a head to serve food and is mounted to a mount at a pivot point. The pivot point provides a mechanical balance and facilities a rugged and washable design.

A weighing module 1 has a force-transmitting linkage 13 arranged between the load-receiving portion 3 of the weighing cell 2 and the load receiver 5, with an overload protection device that precisely maintains its position being an integral part of the force-transmitting linkage 13. By means of a positioning element 7, 107, 207, the load receiver 5 is positioned without play relative to the load-receiving portion 3 in the plane that extends orthogonal to the load direction, and the load receiver 5 is also guided in the load direction without play. When forces in excess of the pre-tension force of the elastic element 8 act on the load receiver 5, the latter has the capability of being displaced in the load direction and to tip in all directions that are orthogonal to the load direction. The housing part 18 serves to delimit at least the range of linear downward deflection as well the tipping movement of the load receiver 5 when the load receiver 5 is exposed to transverse forces and to overloads. The rotation constraint 20 is rigidly connected to the load receiver 5 and engages a housing-connected recess 21. To position the load receiver 5 relative to its operating environment, a positioning device 16 is provided, whose central longitudinal axis coincides with the central longitudinal axis of the load receiver 5.

A weighing scale has a housing (1) that encloses a force transducer (4). A load-transmitting member (9) is connected to the force transducer (4) and passes through an opening to the outside of the housing to transmit the weighing load to the force transducer. An elastic device is interposed between a fixed part that is attached to the housing (1) and a movable part that is attached to the load-transmitting member (9). The elastic device is preferably hollow and controllably expandable and contractible by injecting and removing a fluid through a conduit system (31-43) with a selectively switchable valve device.
